Gas turbine engine can be suitable for any amount of commercial Application, the All aspects of (comprising the conveying of oil and natural gas, collection, storage, extraction and lifting) of such as oil and natural gas industry, power industry, cogeneration of heat and power, Aero-Space and other carriers.
With reference to Fig. 1, gas (being generally air 10) enters entrance 110 as " working fluid ", and is compressed by compressor 200.In compressor 200, working fluid is compressed by a series of compressor disc assembly 220 in annular flow path 115.Especially, air 10 compresses in " level " through numbering, and these levels are associated with each compressor disc assembly 220.Such as, " the 4th grade of air " can be associated with the 4th compact disk assembly 220 on downstream or " backward " direction, advances from entrance 110 towards venting gas appliance 500).Similarly, each turbine disc assemblies 420 can be associated with the level through numbering.
Once pressurized air 10 leaves compressor 200, it enters into burner 300, spreads there and adds fuel.Air 10 and fuel to be ejected in firing chamber 390 by fuel injector 310 and to light.After combustion reaction, from the fuel/air mixture of burning, extract energy by every one-level of a series of turbine disc assemblies 420 via turbine 400.
Then, Exhaust Gas 90 can carry out spreading and guide in exhaust collector 520 in exhaust diffuser 510.The Exhaust Gas 90 of the axial direction from exhaust entrance 530 place is rebooted the radial direction at exhaust outlet 522 place by exhaust collector 520.Exhaust collector 520 can guide Exhaust Gas 90 in air outlet duct system, to be discharged in air by Exhaust Gas 90.Air outlet duct system can process Exhaust Gas 90 further, to reduce noxious emission and/or reclaimed heat from Exhaust Gas 90 before Exhaust Gas 90 is discharged into air.
At the run duration of gas turbine engine 100, exhaust collector 520 may suffer due to inner back pressure and natural frequency excitation cause heavily stressed.The large flat site of exhaust collector 520 may easily deform due to heavily stressed cause and high cycle fatigue lost efficacy.This high cycle fatigue lost efficacy and may cause the effusion of crackle and hot exhaust gas.
First profiled section 562 and the second profiled section 572 have rigidity and resonant frequency, encourage and high cycle fatigue lost efficacy with the natural frequency of every side of farthest reducing the side plate 560 between exhaust outlet 522 and circumferential section 569.The curvature of the first profiled section 562 and the second profiled section 572 can reduce the amount of deflection of side plate 560, and can reduce the average stress of side plate 560.The curvature of the first profiled section 562 and the second profiled section 572 also can increase the rigidity of side plate 560, and this can reduce alternating stress and can increase the natural frequency of side plate 560.The natural frequency increasing side plate 560 can make mode excitation more difficult.
The rigidity increased due to the curvature of the first profiled section 562 and the second profiled section 572 can reduce or prevent the possibility that high cycle fatigue lost efficacy; this can improve the reliability of exhaust collector 520, and can prevent the disorderly closedown of gas turbine engine 100.
Header board 540, rear plate 550 and side plate 560 are thickened the rigidity that can also increase exhaust collector 520.In addition, the radius increasing reinforcer (such as the first side reinforcer 568 and the second side reinforcer 578) can increase the area inertia moment of reinforcer, thus increases the rigidity of exhaust collector 520 further.
Aforementioned detailed description is only exemplary in essence, and is not intended to restriction the present invention or application of the present invention and purposes.Described embodiment is not limited to use in conjunction with the gas turbine engine of particular type.Therefore, although the present invention describes and describes specific gas turbine engine for convenience of explanation, but it will be understood that, can implement with other configurations various according to exhaust collector of the present invention, can use together with the gas turbine engine of various other types, and can use in the machine of other types.In addition, the restriction of any theory being undesirably subject to aforementioned background art or present in describing in detail.It is also understood that diagram can comprise the size exaggerated and shown object of reference is described better, and do not think restrictive, unless clearly stated like this.
